CLN 1.0 Progress Report

The CLN 1.0 Progress Report was released in 2014 and highlights the achievements made since the 2011 release of the CLN. Progress is tracked through four conservation indicators and fourteen progress metrics.

CLN 1.0 Report

The CLN was released in 2011 after a 5-year process with involvement from 125 organizations and agencies. It details the methods used to identify protection targets and goals, and the steps necessary for implementation and interpretation of the CLN as both a vision and guide for Bay Area biodiversity conservation.

Glossary

Bayland Habitats

Areas of historic tidelands that lie between the elevations of the high and low tides, including those areas that would be covered by the tides in the absence of levees and other structures. These lands were the focus of the Baylands Ecosystem Habitat Goals, a regional, ecosystem-based vision for habitat protection.

Biodiversity

The complex of living organisms, their physical environment, the interactions among these organisms, and how they array themselves in the physical environment (Noss 1990, Redford and Richter 1999).

Conservation Lands

Areas protected for natural resource values by public purchase or easement, or private lands with a cooperative agreement and some level of stewardship for biodiversity.

Conservation Lands Network

This network (also called the CLN) identifies areas that support irreplaceable, rare, and endemic plant and animal species, while also encompassing common plant and animal species. The CLN meets the conservation goals for the vast majority of nearly 1,400 vegetation type and fine filter species targets, is relatively well-connected, and explicitly includes the stream and riparian network.

Conservation Planning

The systematic process of identifying areas important for conserving biological diversity or other open space values. The result of this planning process is a network of lands that best conserves all elements of biodiversity within the planning area.

Linkage

A landscape connection that facilitates wildlife movement between habitat areas that is essential for maintaining biodiversity and healthy ecological processes.

Subtidal Habitats

All of the submerged area beneath the bay's water surface including mud, shell, sand, rocks, artificial structures, shellfish beds, eelgrass beds, macroalgal beds, and the water column above the bay bottom. The focus of the San Francisco Bay Subtidal Habitat Goals Project.

Upland Habitats

As used in this project, refers to all habitats found above the baylands, which were the subject of the Baylands Ecosystem Habitat Goals and therefore not included in the Upland Habitat Goals Project.
